Improvement of Physicochemical Properties in Dredging Areas of Dianchi Lake, China

摘要

As being a vital role affecting the water quality and stimulating the circulation of pollution in native lake, the physicochemical properties of water and the surface sediments in Dianchi Lake dredging area were investigate to determine the level of physicochemical properties of the dredging area, and to evaluate the effects of dredging project. The results showed that the physicochemical properties indicated a more seriously polluted state in Caohai. The effectiveness of dredge work in Caohai was ignorable comparing to Waihai, but it was more obvious in the sediment than in water.
